It's hard to know without knowing what you want to order. If I were you, I'd take each item you want to purchase individually and then subtract ten and figure the shipping on that amount. Do it for each of the things you want, and then add them up. Compare that with your one big order, figuring in shipping, and then you'll know. My gut reaction is that unless you're getting a big ticket item, smaller orders with $10 off are your best bet.
